chain too tightly. When cold, it should be possible to lift the chain in the middle of the guide bar approx
5 mm. Tighten the guide bar cover (6) securely.
When warm, the saw chain will expand and slacken and there is a danger of it jumping off the rail
altogether if improperly tensioned. Re-tension if necessary. If the saw chain is re-tensioned when hot,
it must be loosened again when the sawing work has been completed. Otherwise, the contraction which
takes place as the chain cools would result in excessively high tension. A new saw chain requires a
running-in period of approx .5 minutes. Chain lubrication is very important at this stage. After running in,
check chain tension and re-tension if necessary.
Filling in chain oil (Fig 4)
To prevent dirt getting inside the tank, clean the oil tank cap (21) before opening. Check the contents of
the oil tank during sawing work by checking the oil gauge (15). Close the oil tank cap tightly and wipe
away any spills.
Securing the extension lead (Fig 6)
Only use extension leads suitable for outdoor use. The cross section of the cable (max. length of exten-
sion cord: 75m) must be at least 1,5 mm 2
. Secure the chainsaw flex to the extension lead by inserting the
extension lead into the strain relief gap of the housing.
Extension leads longer than 30 m should have a cross section of at least 2,5 mm
2
to avoid reducing the
performance of the chainsaw.
Chain lubrication
To prevent excessive wear, the saw chain and guide bar must be evenly lubricated during operation.
Lubrication is automatic. Never work without chain lubrication. If the chain runs dry, the entire cutting
apparatus will quickly become severely damaged. It is therefore important to check both chain lubrication
and the oil gauge before every use (Fig. 4).
Never use the saw when the oil level is below the “Min.” mark.
• Min.: When only approx. 5 mm of oil is visible at the lower rim of the oil gauge (15), you must top up
with oil.
• Max.: Top up with oil until the window is full.
Checking the automatic lubrication
Before commencing work, check the automatic chain lubrication and oil gauge. Switch on the chain saw
and hold it above the ground. Be careful not to allow the chain saw to touch the ground. For safety
reasons it is best to keep a clearance of at least 20 cm. If you now see growing traces of oil, the chain
lubrication system is working correctly. If there are no traces of oil at all, try cleaning the oil outlet
(Fig 2, C), the upper chain tensioning borehole (E) and the oil duct, or contact your Customer Service.
Chain lubricants
The service life of saw chains and guide bars depends to a large extent on the quality of the lubricant
used. Old oil must not be used! Use only environment-friendly chain saw lubricant.
Guide bar
The guide bar (7) is subjected to especially severe wear and tear at the nose and the bottom. To avoid
one-sided wear and tear, turn the guide bar over every time when you sharpen the chain.
Chain wheel
The chain wheel (16) is subjected to especially high wear and tear. If you notice deep wear marks on the
teeth, the chain wheel must be replaced. A worn chain wheel curtails the service life of the saw chain.
Have the chain wheel replaced by a specialist dealer or your Customer Service.
